Description
- 1. Field of the Invention
- The invention generally relates to a paper holes punching machine. More particularly, the invention relates to a multiple holes punching machine in which the holes-punching unit may be fitted to the main body more easily and more securely and in which the borderline distance may be adjusted easily.
- 2. Description of the Prior Art
- With regard to the types of holes punching machines, there are two holes punching machine (which may be operated manually) and multiple holes punching machine.
- Because multiple holes punching machine needs more power in its operation and is structurally more complex, it is larger. The purchase of two or more of such machines with different holes punching capacity would cost more money and take up more space.
- Therefore, the multiple holes punching machine may have the design that the holes-punching unit is detachable from the main body. A manual stick is provided on either side of the main body so that, as the holes-punching unit needs to be replaced, another holes-punching unit may be fitted to the main body easily and accurately through the engagement between the two manual sticks and the slot provided on either side of the holes-punching unit. Accurate alignment of the engagement is difficult to achieve. In addition, because there is no design to assure the tight connection between the holes-punching unit and the main body, the punching action would make the engagement out of alignment and thus would worsen the precision of holes punching.
- To adjust the borderline distance, a borderline distance adjusting stick is usually provided in the holes-punching unit. However, in order to adjust the borderline distance, a user has to open up the holes-punching unit or detach the holes-punching unit from the main body. Therefore, the adjustment of borderline distance is unnecessarily more difficult and more time-consuming.
- An object of the present invention is to provide a multiple holes punching machine in which the holes-punching unit may be fitted to the main body more easily and more securely.
- Another object of the present invention is to provide a multiple holes punching machine in which the borderline distance may be adjusted easily.
- To reach these objects, the multiple holes punching machine of the present invention is disclosed. The multiple holes punching machine of the present invention comprises a main body and a holes-punching unit. The main body may be placed on top of a flat surface stably and can generate power. The holes-punching unit is detachably fitted to the main body and can use the power generated by the main body to carry out the holes-punching operation of paper. The main body comprises a first side board and a second side board. A positioning slot is provided on the inner side of the first side board and at least a sloped surface is formed in the positioning slot. A manual stick is pivotally connected to the second side board and may be rotated. An engagement portion is provided on the stick. The holes-punching unit comprises a first side board, a second side board, a border adjusting assembly and a plurality of holes-punching members. A male positioning portion is provided on one end of the first side board and a sloped surface and an arc-shaped surface are provided on the male positioning portion. A protruding surface is formed on the arc-shaped surface. Therefore, as the holes-punching unit is fitted to the main body, accurate positioning may be achieved by the sloped surface of the male positioning portion and the sloped surface of the positioning slot and secured attachment may be accomplished by the engagement portion of the stick and the protruding surface.
- The holes-punching unit of the present invention comprises a first side board, a second side board, a plurality of holes-punching members and a borderline distance adjusting assembly. Pluralities of elongated slots are provided on the inner surface of the first side board and are equally spaced and are slant. A plurality of borderline distance adjusting hole sets are also provided on the inner surface of the first side board and the hole sets and the elongated slots are arranged in an alternating manner. Each hole set has equal or more than two adjusting holes and the hole sets are slant and equally spaced. The second side board is connected with the first side board and a space is formed between the second side board and the first side board. Pluralities of holes-punching members are disposed on the second side board and would move into the space when an external force exerts on the holes-punching members. The borderline distance adjusting assembly has a sliding stick, which is disposed in the space. A plurality of sliding pieces and a plurality of positioning balls are provided on the sliding stick. The sliding stick is positioned by the engagement between the sliding pieces and the elongated slots and the engagement between the positioning balls and the adjusting holes.

stick 231 is provided on the borderlinedistance adjusting assembly 23. A plurality of slidingpieces 232 are provided on the slidingstick 231 and each of the slidingpieces 232 corresponds to one of theelongated slots 215. A plurality ofpositioning balls 233 are also provided on the slidingstick 231 and each ofpositioning balls 233 corresponds to one of the hole sets. Each of thepositioning balls 233 is pushed inwards if an external force exerts on it and stays outwards if there is no external force exerting on it. The slidingstick 231 is disposed in the space formed between thesecond side board 22 and thefirst side board 21 and is positioned by the engagement between the slidingpieces 232 and theelongated slots 215 and the engagement between thepositioning balls 233 and the adjusting holes 216. - We will elaborate on how the multiple
holes punching machine 100 is assembled and used in the following. - In assembly, first, fit the hole-punching
unit 20 to themain body 10 by engaging themale positioning portion 211 with the positioning slot 111 (as shown inFIG. 10 ). Through the engagement of the slopedsurface 212 and thesloped surface 112, the hole-punchingunit 20 may be fitted to themain body 10 swiftly and easily. Then, rotate themanual stick 121 towards the arc-shaped surface 213 (as shown inFIGS. 11 and 12 ) so that theengagement portion 122 of thestick 121 may engage with the arc-shapedsurface 213 and tightly press against the protruding surface 214 (as shown inFIGS. 13 and 14 ). Therefore, the hole-punchingunit 20 may be tightly connected with themain body 10. Therefore, accurate positioning and alignment may be achieved by the slopedsurface 212 of themale positioning portion 211 and thesloped surface 112 of thepositioning slot 111 and secured and tight attachment may be accomplished by theengagement portion 122 of thestick 121 and the protrudingsurface 214. - To adjust the borderline distance, move the sliding
stick 231 of the hole-punchingunit 20 along theelongated slots 215 so that thepositioning balls 233 may move to a different level in theholes 216. In this manner, borderline distance may be adjusted easily and swiftly. - From the above, we can see that the multiple holes punching machine of the present invention meets the relevant patent requirements. It is hoped that the patent application will be approved.
- Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
